Newell was a homicide detective and a 24-year veteran of the Metropolitan Police Department.

Within that time, he helped solve the murder of Sheila Hill's grandson.

"I had to pay tribute to the man who solved the crime and a family friend," she said.

Seventeen-year-old Julian Agurs was walking with his friends in 2008 when he was killed in the crossfire.

Sheila Hill has felt indebted to Newell ever since they found her grandson's killer.

"My whole being, my life. The man had integrity. I've known him since childhood. But to solve my grandson's murder I say thank you, Jesus. Thank you for him. Thank you."

Newell leaves behind 6 children and 5 stepchildren including the one who's now charged with his murder.

"He spent his whole life protecting other people and keeping them safe. He lost his life the same way he spent his life protecting others," Chief Lanier said. "It's devastating for us in law enforcement. It's the hardest thing to understand. "

Detective Newell will be buried next Wednesday at Cheltenham Veterans Cemetary.

His stepson, Antwan James, is being held without bond on first degree murder.
